Investment Q&A

Perhaps one lesson/reminder is that volatility comes for almost all stocks eventually. Operating businesses are dynamic and things change and evolve at the business and economic level, so rough patches are hard to avoid. Of course, short term volatility and speed bumps does not on its own make a business 'bad'. 

The other main thing we would note is just the importance of rebalancing. In most of these cases, depending on ones holding period, modest rebalancing and profit taking would have likely stunted much of the pain in these names. Even if maintained at a full position.

Finally the importance of diversification where holding names that are in a drawdown is obviously not ideal but also makes it something that a portfolio can bounce back from.
