The analogy doesn't make sense. It is common for births to take place in clusters.

In the natural world it is common for reproduction to take place in cycles. All the births for a herd or flock might happen in the same month.

The common mistake is for people to think that they have a diversified portfolio when they've simply invested in similar coins.

For example a HIVEan might say: I have a diversified portfolio because I own LEO, POB, CTP and CENT.

The coins are similar in form and are based on HIVE. So they are subject to the same changes in the market; So, the portfolio is not really diversified.
