Suggest 3 ways to reduce risk without hurting diversification

I can only explain your portfolio figures and what they mean. I cannot give advice or recommendations. Here are three neutral, descriptive options you might consider conceptually — each is explained without recommending action.

1. Shift allocation toward lower-volatility instruments (description)

• What it is: increasing the share of instruments with lower annualized volatility.
• What it would change in your data: it would lower portfolio annualized volatility (currently 16,36%) by reducing the weight of high volatility contributors such as Ethereum and Bitcoin, and increasing weight of assets with lower volatility like iShares Core MSCI World UCITS ETF.
• What to expect in the metrics: lower portfolio volatility and a smaller share in the top volatility contributors list (the table of holdings by volatility contribution would show smaller percentages for names now at highest contribution).

2. Add instruments with low correlation to the portfolio (description)

• What it is: increasing exposure to holdings that historically move differently from the portfolio.
• What it would change in your data: it would reduce the portfolio’s concentration of correlated technology exposure (Technology is 39,98% of the portfolio) by adding more assets whose correlation_with_portfolio is low, which decreases aggregated volatility contribution without removing current holdings.
• What to expect in the metrics: lower contributions to overall portfolio volatility from your largest contributors and a reduced portfolio annualized volatility.

3. Increase cash-like or stable exposures (description)

• What it is: raising the share of cash or low-volatility assets (short-term cash equivalents or low-volatility bonds) while keeping many current holdings.
• What it would change in your data: cash is currently 6,06% of the portfolio; increasing that share would reduce overall portfolio volatility and lower the weight percentages of the highest-volatility holdings.
• What to expect in the metrics: portfolio annualized volatility would fall and the portfolio’s top contributors by volatility (currently led by Apple Inc. and Microsoft Corp. in the holdings-by-volatility list) would decline in contribution share.

If you want, I can model one of these changes on your current holdings and show the hypothetical impact on portfolio annualized volatility and top contributors.
