这个视频里列举了六种方法。有谁能帮助分析一下第三种（PVF）的优缺点。谢谢。
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
如果这是401K里的雇主公司的股票，可以 search net unrealized appreciation on youtube
