Whenever markets decline, talk invariably turns to "cash on the sidelines" and the impact it will have when it returns to the markets. Annaly Capital Management has a commentary that shows several charts regarding "cash on the sidelines". The essence is that cash never leaves the sidelines! I would guess that the cash holding is a policy decision and the few investors that do move to all cash at some point during a downturn don't materially impact the aggregate level of cash. This is an interesting chart from Annaly Capital Management:
To me, it highlights clearly the introduction of leverage into the markets in the late 1970s (Milken?!) and the continued increase in leverage until the mid 90s at which point it more or less stabilizes just over 20%. Cash collateral again declines during 2001 (hedge fund boom) and bottoms last year before turning back up, much as it did in 2000 (post interet bubble burst). Clearly, there remains significant leverage in the equity markets. I think the question is will this de-levering trend continue or will we see a reversal as we did in 2001/2002? If market participants continue to de-lever, markets are unlikely to move materially higher - it stands to reason that "un-levered" markets will trend consistent with earnings trends. If leverage isn't reduced, then we could see markets continue to accelerate a rate greater than earnings growth (more dollars translates to greater demand). I don't know the answer but I do think it needs to be an important consideration for any forecasts of future returns.
I expect participants will continue to de-lever in anticipation of potential inflation (which will increase borrowing costs) and because of a desire to improve balance sheets and reduce risk. To what point I don't know, maybe to 25% from roughly 20% now. That would suggest a 25% reduction in debt still to come. That should dampen returns but suggests that we won't see a true 1-1 relationship between financial market growth and earnings growth. In other words, it is possible that we won't see P/Es return to historical averages (such as 15 on the S&P) but rather some level above that.
Currently, the S&P is trading at 19.6X bottom-up 2009 estimates and 14.5X 2010 estimates. P/Es tend to contract after the economy troughs as real results start to meet and exceed expectations upon which prices are set. If P/Es contract to 15 (historical average), the potential year-end 2010 S&P index level would be 1094. I think many would see that as reasonable given the current economic environment of slow improvement in fundamentals. But if leverage doesn't decline as much as people, including me, have expected, the P/E ratio may contract only to, say, 17.3 (50%). Then the S&P might close 2010 at 1262. That would be a roughly 19% gain over the next 15 months.
I will continue to hedge downside risk but will be paying close attention to the ratio highlighted in the chart above (as well as to overall economic data). If 09 earnings do hit current S&P estimates, then it may be time to revise my personal outlook.
