Hindsight bias
Picking Nvidia or Bitcoin today means picking known winners. Back then, nothing set them apart from hundreds of assets that went nowhere or vanished.
Holding on was the real test
The result assumes you never sold, including through the drawdowns shown above. Very few investors actually do.
The broad market, no bet required
The MSCI World never makes headlines, but it does not require guessing the winner. It is the fairest yardstick for any pick.
Method: past performance, computed from split-adjusted monthly closing prices (intra-month lows are smoothed out). Converted at each month’s exchange rate; no fees, no taxes. The MSCI World benchmark is the price index, excluding dividends. Sources: Yahoo Finance (prices, exchange rates, US Treasury bills), Eurostat (inflation), published regulated rates (Livret A).
