Answer: Yes, it is true that vault strategies can sometimes cause a dip in the share price of a vault, but this is typically a short-term phenomenon. Most vault strategies are designed to maximize risk-adjusted yield, so in the long-term, the share price should remain relatively stable. It is also important to note that while some vault strategies can cause a dip in the share price, they are not currently being used in the DeFi space. Therefore, overall, it is safe to say that investing in vaults can be a great way to enjoy the best risk-adjusted yield in DeFi.

Ok :)
