I've seen lots of articles discussing minimizing downside risk with purchasing covered puts, even long term (LEAPS) with 1+ year timeframes. There's even good traffic for index leaps, specifically for the S&P500.
However, I haven't seen any of this address Sequence of Return Risk in particular. As the first few years' performance are the strongest indicator of overall success, with heavy losses in the first few years being the primary sign of portfolio failure, it might make sense to pay a premium in order to limit the risk of this happening.
While considering this, I've noticed a few issues:
The only index I see with good activity on the options market, at least available publicly, is SPY - the S&P 500 etf. There's some activity on VWO, the emerging markets ETF, however, I don't see any good options for hedging VTI (a total US market ETF) or VXUS (total non-US international index). This makes it significantly less useful, especially when you consider that the S&P500 tends to do better in downturns than VTI.
Secondly, this puts you at greater risk of a flat/very slightly increasing market over the first few years. As you've added a ~3% (guesstimate) cost to hedge against a loss of >5-10% in the market, you would have an effective 7% withdrawal rate instead of the standard 4%.
This could be covered somewhat by limiting your upside, selling covered calls. I've done less research on this side, so I'd love some input on how much of this cost could be recuperated this way.
The final issue is deciding how long this strategy would be prudent. Set a number of years? Set an inflation-adjusted portfolio value that you would consider "safe" to stop paying the premium?
Has anyone else here considered something like this, and resolved any of the issues mentioned above (or that I'm failing to see)?
