這個視頻裏列舉了六種方法。有誰能幫助分析一下第三種（PVF）的優缺點。謝謝。
1. Sell stock (might spread to multi-year if needed)
2. Hedging with option (floor and/or collar)
3. Moneytize: private forward contract (PVF aggreement)
4. Borrow and diversify (on margin)
5. Exchange funds (LP), defer paying capital gain tax on money contributed and shares received to 7 years later
6. Donate to charity (CRT and CLT), private foundation
如果這是401K裏的雇主公司的股票，可以 search net unrealized appreciation on youtube
