I wouldn't change anything now, that makes a paper loss a real loss.  

But- you need to diversify your investments. If you lost 33% and it scares you, you're way too exposed to speculative, risky holdings. Yes, the profits can be very good, but losses are more significant in most people's views when they occur than the possible positives as the market swings back.

If anything, go as contrarian as you can stand and buy in a bear market.

Not surprised that you assign a short term standard to what is a long term phenomenon.

When your success compares to Elon Musk then your comparison would be meaningful. As it is, it's coincidence.
