| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? In the first half of 2024, the Guinness Atkinson Alternative Energy Fund produced a total return of -3.67% vs the MSCI World Index (net return) of 11.75%. What affected the Fund's performance? Fund performance can be attributed to the following. Within the portfolio, the strongest performers included: Our electrical equipment names Eaton, Hubbell, Schneider and Itron all performed strongly driven by an acceleration in global electrification activity and the resolution of supply chain issues which allowed them to pass on inflationary pressures and therefore maintain operating margins. Hubbell and Eaton delivered good earnings upgrades resulting from the re-industrialisation of the United States as well as the move to electrification. The positive order book inflection continues at Eaton. Within displacement, Trane Technologies and Installed Building Products (IBP) delivered well. Trane was helped also by regulatory changes and its positioning with respect data centres. In addition, First Solar shares were up 30.9% in 1H as the company was seen as a key beneficiary when local content IRA tax credit definitions were clarified while NextEra performed well after delivering an upbeat "Renewables Development Day" for investors. Sectors and companies in the portfolio that were relatively weaker over the period included: The electrification sub sector, with EV component and lithium-ion battery manufacturers suffering from delays in EV launch schedules, margin pressure and the threat of increasing Chinese competition. Nibe shares were under pressure as the heat pump market remains overstocked at the distributor level. Canadian Solar delivered negative contribution as module prices reached record lows while US residential solar companies continued to face a prolonged de-stocking headwind. A number of our generation companies delivered negative contribution as interest rate cuts did not crystalise while Sunnova weakened through the period as the US residential solar business remained under pressure. |

In the first half of 2024, the Guinness Atkinson Asia Focus Fund produced a total return of 0.34% vs the MSCI AC Far East ex Japan Index (net return) of 7.98%. What affected the Fund's performance? Fund performance can be attributed to the following: Overall Fund performance was primarily driven by asset allocation, with overweighting to Information Technology and zero weighting to Real Estate and Materials driving the highest contributions to the Fund's total returns. Overweighting in Health Care and Consumer Discretionary caused the largest drags to performance contribution. Communication Services was the third largest drag, although this was driven by stock selection (underweight Tencent and overweight Baidu) which more than offset positive asset allocation effects. Stock selection in Health Care and Consumer Discretionary were also drags on performance, driven by China Medical Systems (-51.62% in USD), Corporate Travel Management (-32.90%), and Hanon Systems (-39.15%). A positive stock selection effect was seen in Financials where China Merchants Bank (+30.34%) and DBS Group (+18.23%) both outperformed. Within Technology, we saw strong performances from TSMC (+54.88%), Applied Materials (+46.12%) and Broadcom (+44.90%). However, under allocation to TSMC caused a drag effect. |

In the first half of 2024, the Guinness Atkinson China & Hong Kong Fund produced a total return of -8.16% vs the MSCI China Index (net return) of 4.74%. What affected the Fund's performance? Fund performance can be attributed to the following: Areas which helped the Fund's performance were: Individual stock returns, led by China Merchants Bank (total return +30.4%), Sany Heavy Industry (+18.7%) and Haier Smart Home (+18.4%). Stock selection in the Real Estate sector, driven by China Overseas Land & Investment (+1.6%) compared to the sector which fell 11.4%. Stock selection in the Consumer Staples sector, led by not holding names such as Kweichow Moutai (-15.2%), Mengniu Dairy (-30.6%) and JD Health (-45.6%). Areas which detracted from the Fund's relative performance were: Offshore stocks outperformed onshore stocks. As the Fund is underweight to the offshore market and overweight to A shares, it benefited from less of the rally in the offshore market. The Fund has an overweight to mid-caps which, along with small caps, have significantly underperformed large caps. Structural underweight to Tencent (total return +28.0%) which is the largest stock in the Index and so the Fund's relative performance benefited less. Underweight to Financials, and more specifically the underweight to the large state-owned enterprise (SOE) banks. The Fund does not hold any of the large SOE banks which have been significant outperformers as a value play. The combined underweight to Materials, Energy and Utilities which have been stronger sectors but where the Fund has no exposure. |

What affected the Fund's performance? Fund performance can be attributed to: The Fund's overweight position to the Information Technology sector, and more specifically the benchmark's top performing Semiconductor industry, was the greatest tailwind to Fund outperformance, driven by both strong allocation and stock selection effects. Strength from Nvidia (+149.5% USD), off-benchmark name TSMC (+68.3% USD) and semi-cap equipment names Applied Materials (+46.1%), KLA (+42.4%) and Lam Research (+36.5%) all contributed positively to Fund outperformance. The Fund also benefitted from strong stock selection within Industrials, where holdings ABB (+27.6% USD) and Schneider Electric (+21.3%) outperformed the broader MSCI World Industrials index by 20.1% and 13.8% respectively. Whilst holding a relatively neutral position to both the Communication services and Healthcare sectors, strength from Meta (+42.7% USD), Alphabet (+30.3%) and Novo Nordisk (+40.5%) drove a strong stock selection effect within these sectors. The Fund benefitted from a zero-weight allocation to Energy, Utilities, Consumer Staples, Materials and Real Estate, which all underperformed the broader benchmark. |

What affected the Fund's performance? Fund performance can be attributed to: The Fund's overweight position to the Information Technology sector, and more specifically the benchmark's top performing Semiconductor industry, was the greatest tailwind to Fund outperformance, driven by both strong allocation and stock selection effects. Strength from Nvidia (+149.5% USD), off-benchmark name TSMC (+68.3% USD) and semi-cap equipment names Applied Materials (+46.1%), KLA (+42.4%) and Lam Research (+36.5%) all contributed positively to Fund outperformance. The Fund also benefitted from strong stock selection within Industrials, where holdings ABB (+27.6% USD) and Schneider Electric (+21.3%) outperformed the broader MSCI World Industrials index by 20.1% and 13.8% respectively. Whilst holding a relatively neutral position to both the Communication services and Healthcare sectors, strength from Meta (+42.7% USD), Alphabet (+30.3%) and Novo Nordisk (+40.5%) drove a strong stock selection effect within these sectors. The Fund benefitted from a zero-weight allocation to Energy, Utilities, Consumer Staples, Materials and Real Estate, which all underperformed the broader benchmark. |

| Factors Affecting Performance [Text Block] | How did the Fund perform during the reporting period? In the first half of 2024, the Guinness Atkinson Renminbi Yuan & Bond Fund produced a total return of -0.62% vs the Hang Seng Markit IBoxx Offshore RMB Overall Index of -0.21%. What affected the Fund's performance? Fund performance can be attributed to the following: Overall Fund performance was primarily driven interest coupons and bonds price gains (+1.85%) but offset in dollar terms by a decline (-2.43%) in the value of the Renminbi vs the US Dollar. The biggest contributor to performance was GLP China Holdings 4% 07/02/2024 (+26.7%). The bond had been exhibiting signs of distress, but the company has been raising liquidity and the price improved. The bond has since matured, on maturity date at par. The macro environment in China has remained testing with consumer sentiment weak, inflation falling and the government very cautious about adding short-term stimulus. |
