Is investing monthly better than investing all at once?

Historically, investing a lump sum right away returns more in most cases, because markets rise more often than they fall. But monthly investing smooths the purchase price, protects against the worst timing and matches how people actually save: from their paycheck, month after month.

How is the annual return calculated?

With spread-out contributions, the multiple of the amount invested does not tell the whole story: the last dollars had only a few months to grow. The IRR (internal rate of return) is the average annual return that, applied to each contribution from its date, produces the final value.

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.
