| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence, particularly in the information technology sector. Emerging markets lagged their developed peers, held back by weakness in China’s recovery and a strengthening U.S. dollar. Although bonds underperformed equities, they still delivered generally positive total returns during the reporting period. Amid economic growth concerns, central banks began to pivot away from higher interest rates to easing monetary policy, causing volatility in Treasury yields. What contributed to performance? Both equities and fixed income advanced for the reporting period. The equity allocation represented approximately 81% of the Fund on average during the reporting period. Equities across regions and capitalizations rose, led by U.S. large-capitalization stocks, which were the largest contributor to the Fund’s return. The information technology sector drove U.S. large-capitalization stocks meaningfully higher, particularly a handful of dominant information technology companies that have been able to rapidly innovate, capture significant market share, and generate substantial profits. International developed stocks benefited from the sharp rally in Japanese shares, supported by central bank actions and improved corporate governance. The bond allocation, which constituted approximately 19% of the Fund on average during the reporting period, U.S. corporate bonds benefited from strong demand and more attractive yields than their government-issued counterparts. What detracted from performance? There were no detractors to the Fund’s performance during the reporting period. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results. | ||

The information technology sector drove U.S. large-capitalization stocks meaningfully higher, particularly a handful of dominant information technology companies that have been able to rapidly innovate, capture significant market share, and generate substantial profits. Across the bond allocation, which constituted approximately 69% of the Fund on average during the reporting period, U.S. corporate bonds benefited from strong demand and more attractive yields than their government-issued counterparts. Maturity-wise, shorter-term issues, those between zero and three years, outperformed longer-term securities. Short-term issues are less sensitive to interest rate changes and benefit from higher yields and lower duration risk. What detracted from performance? There were no detractors to the Fund’s performance during the reporting period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence, particularly in the information technology sector. Emerging markets lagged their developed peers, held back by weakness in China’s recovery and a strengthening U.S. dollar. Although bonds underperformed equities, they still delivered generally positive total returns during the reporting period. Amid economic growth concerns, central banks began to pivot away from higher interest rates to easing monetary policy, causing volatility in Treasury yields What contributed to performance? Both equities and fixed income advanced for the reporting period. The equity allocation represented approximately 61% of the Fund on average during the reporting period. Equities across regions and capitalizations rose, led by U.S. large-capitalization stocks, which were the largest contributor to the Fund’s return. The information technology sector drove U.S. large-capitalization stocks meaningfully higher, particularly a handful of dominant information technology companies that have been able to rapidly innovate, capture significant market share, and generate substantial profits. International developed stocks benefited from the sharp rally in Japanese shares, supported by central bank actions and improved corporate governance. Across the bond allocation, which constituted approximately 38% of the Fund on average during the reporting period, U.S. corporate bonds benefited from strong demand and more attractive yields than their government-issued counterparts. What detracted from performance? There were no detractors to the Fund’s performance during the reporting period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence, particularly in the information technology sector. Although bonds underperformed equities, they still delivered generally positive total returns during the reporting period. Amid economic growth concerns, central banks began to pivot away from higher interest rates to easing monetary policy, causing volatility in Treasury yields. What contributed to performance? Both equities and fixed income advanced for the reporting period. While the equity allocation represented approximately 41% of the Fund on average during the reporting period, it was the largest contributor to returns. Equities across regions and capitalizations rose, led by U.S. large-capitalization stocks, which were the largest contributor to the Fund’s return. The information technology sector drove U.S. large-capitalization stocks meaningfully higher, particularly a handful of dominant information technology companies that have been able to rapidly innovate, capture significant market share, and generate substantial profits. Across the bond allocation, which constituted approximately 58% of the Fund on average during the reporting period, U.S. corporate bonds benefited from strong demand and more attractive yields than their government-issued counterparts. Maturity-wise, shorter-term issues, those between zero and three years, outperformed longer-term securities. Short-term issues are less sensitive to interest rate changes and benefit from higher yields and lower duration risk. What detracted from performance? There were no detractors to the Fund’s performance during the reporting period.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence, particularly in the information technology sector. Emerging markets lagged their developed peers, held back by weakness in China’s recovery and a strengthening U.S. dollar. Although bonds underperformed equities, they still delivered generally positive total returns during the reporting period. Amid economic growth concerns, central banks began to pivot away from higher interest rates to easing monetary policy, causing volatility in Treasury yields. What contributed to performance? Across the bond allocation, which constituted approximately 73% of the Fund on average during the reporting period, high-yield corporate bonds contributed the most to the Fund’s return. Resilient corporate profits and an increasing risk appetite among investors supported high-yield bonds. As investors searched for yield, preferred and income securities from the United States that offer income stability benefited. Equities across regions and capitalizations rose, led by U.S. large-capitalization stocks, which were the largest contributors to the Fund’s return. The information technology sector drove U.S. large-capitalization stocks meaningfully higher, particularly a handful of dominant information technology companies that have been able to innovate rapidly, capture significant market share, and generate substantial profits. What detracted from performance? The modest allocation to real estate investment trusts (“REITs”) detracted from the Fund’s performance during the reporting period. REITs were faced with a challenging landscape that included higher mortgage rates, reduced demand, and macroeconomic uncertainty.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence (“AI”), particularly in the information technology sector. In a risk-on environment, stocks with exposure to high volatility, those with significant degrees of price changes, outperformed those with lower volatility characteristics The U.S. Federal Reserve Bank left rates on hold during the 12-month period as the central bank sought greater confidence in slowing inflationary pressures. As inflation measures became more subdued, expectations increased for interest rate cuts in 2024. What contributed to performance? The information technology sector contributed the most to the Fund’s return during the reporting period. Performance was largely driven by a handful of dominant information technology companies that have been able to rapidly innovate, capture significant market share, and generate substantial profits. The software and services industry boosted performance, as several information technology consulting services companies capitalized on growing AI enthusiasm and increased cloud computing demand. Software companies that offer AI solutions via cloud-based infrastructure particularly benefited, as companies sought to incorporate AI without having to invest in data centers. Healthcare stocks also contributed to the Fund’s performance, most notably biotechnology stocks that stand to benefit from potential AI enhancements. What detracted from performance? The market environment during the reporting period, especially in 2023, was risk-on, reflecting investors’ positive sentiment. As expected, lower-volatility stocks, or those that experience less price swings, lagged the broader market.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence (“AI”), particularly in the information technology sector. In a risk-on environment, stocks with exposure to high volatility, those with significant degrees of price changes, outperformed those with lower volatility characteristics. The U.S. Federal Reserve Bank left rates on hold during the 12-month period as the central bank sought greater confidence in slowing inflationary pressures. As inflation measures became more subdued, expectations increased for interest rate cuts in 2024. What contributed to performance? The information technology sector contributed the most to the Fund’s return during the reporting period. The software and services industry boosted performance, as several information technology consulting services companies capitalized on growing AI enthusiasm and increased cloud computing demand. Software companies that offer AI solutions via cloud-based infrastructure particularly benefited, as companies sought to incorporate AI without having to invest in data centers. Financial stocks also contributed to the Fund’s performance, most notably insurance companies in the property and casualty segment. What detracted from performance? The market environment during the reporting period, especially in 2023, was risk-on, reflecting investors’ positive sentiment. As expected, lower-volatility stocks, or those that experience less price swings, lagged the broader market. A small allocation to equity real estate investment trusts (“REITs”) minorly detracted from the Fund’s performance during the reporting period. REITs were faced with a challenging landscape that included higher mortgage rates, reduced demand, and macroeconomic uncertainty. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence (“AI”) particularly in the information technology sector. The U.S. Federal Reserve Bank left rates on hold during the 12-month period as the central bank sought greater confidence in slowing inflationary pressures. As inflation measures became more subdued, expectations increased for interest rate cuts in 2024. Despite strong economic data, companies saddled with high debt or little to no growth were discounted as a result of restrictive rates and persistent inflation, while companies with strong balance sheets or earnings were rewarded. What contributed to performance? Stronger-than-expected economic and earnings growth helped large-capitalization equities during the reporting period. The information technology sector contributed the most to the Fund’s return, as the ongoing trend of AI adoption created strong momentum within the sector, particularly among mega-capitalization companies. Within the sector, companies responsible for the manufacturing of the semiconductor chips needed to power AI strongly contributed to performance, aided by increased demand for their products and strong tariffs limiting imports. The industrials sector also contributed to the Fund's return, with strong performance in the capital goods industry. Aerospace and defense companies benefited from increasing air travel demand, continued global unrest, and expansion efforts during the reporting period. Within the healthcare sector, pharmaceutical companies producing the increasingly popular GLP-1 drug therapies for chronic weight management also contributed to performance. What detracted from performance? As both stocks and bonds enjoyed healthy returns for the reporting period ended July 31, 2024, there were no material detractors to the Fund’s return. The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence particularly in the information technology sector. The U.S. Federal Reserve Bank left rates on hold during the 12-month period as the central bank sought greater confidence in slowing inflationary pressures. As inflation measures became more subdued, expectations increased for interest rate cuts in 2024. Despite strong economic data, companies saddled with high debt and/or little to no growth were discounted as a result of restrictive rates and persistent inflation. What contributed to performance? Stronger-than-expected economic and earnings growth helped the performance of U.S. large-capitalization equities during the reporting period. The financials sector contributed the most to the Fund’s return, as healthy bank balance sheets and the prospect of interest rates remaining higher for longer benefited the sector. Within the financials sector, enhanced wealth management fees positively impacted asset management firms. The industrials sector also contributed to the Fund’s return, with strong performance in the capital goods industry. Aerospace and defense companies benefited from increasing air travel demand, continued global unrest, and expansion efforts during the reporting period. Within the information technology sector, the ongoing trend of AI adoption created solid momentum and drove returns. What detracted from performance? The consumer staples sector detracted the most from the Fund’s return during the reporting period, particularly within the food, beverage, and tobacco industry. As economic conditions softened but pricing pressures remained elevated, consumers continued to trade down for cheaper products at grocery stores.

| Factors Affecting Performance [Text Block] | How did the Fund perform last year? Slowing inflationary pressures and hopes of interest rate cuts drove global equities higher during the reporting period. U.S. stocks powered markets higher, driven by the enthusiasm for artificial intelligence (“AI”) particularly in the information technology sector. The U.S. Federal Reserve Bank left rates on hold during the 12-month period as the central bank sought greater confidence in slowing inflationary pressures. As inflation measures became more subdued, expectations increased for interest rate cuts in 2024. What contributed to performance? The financials sector contributed the most to the Fund’s return, as healthy bank balance sheets and the prospect of higher-for-longer interest rates benefited the sector during the reporting period. Elevated interest rates allowed banks to lend at improved margins, increasing their profitability. The performance of asset management firms gained on enhanced fees from wealth management units. The information technology sector also contributed to performance. The ongoing trend of AI adoption created strong momentum across the sector, and firms benefited from the increased investment in technology spending. Companies that provide hardware and storage gained on greater demand for storage solutions, innovations, and solid growth prospects. What detracted from performance? The consumer staples sector detracted the most from the Fund’s return during the reporting period, most notably drug retail companies. Drugstore chains experienced slower-than-expected patient growth and difficulties stemming from changes to the Medicare reimbursement program. Medicare is the single largest payer for healthcare services in the United States. In the healthcare sector, some of the larger pharmaceutical companies were pressured as they faced upcoming patent expirations and waning demand for COVID-related treatments.
