This post is a guest con­tri­bu­tion by Vitaliy N. Kat­senel­son*, author of Active Value Invest­ing: Mak­ing Money in Range-Bound Mar­kets and direc­tor of research at Invest­ment Man­age­ment Asso­ciates.

The stock mar­ket has dropped. Cor­po­rate prof­its have col­lapsed. And profit mar­gins have reverted toward the mean. What is next?

Before I dive into the dis­cus­sion, let me explain the chart below, which I named appro­pri­ately, “The pain of mean reversion.”

I looked at reported earn­ings for S&P 500 and com­pared them to the “aver­age case” earn­ings sce­nario. In the “aver­age case” sce­nario I took reported earn­ings of S&P 500 in the early 1990s and grew them at 6% — an aver­age growth rate of GDP over the last cen­tury which hap­pens to be the same as earn­ings growth for stocks dur­ing the same century.

If the econ­omy had no cycli­cal­ity and profit mar­gins remained con­stant, you would see nice, steady growth earn­ings for S&P 500 stocks like the one in the chart.

Of course, profit mar­gins do not stay con­stant — they fluc­tu­ate, thus actual earn­ings swing above and below the steady 6% trend line.

How far will earn­ings drop?
You’ll never go wrong quot­ing Mark Twain when he said “His­tory doesn’t repeat itself, but it does rhyme.” Our chal­lenge as investors is to look at the past and fig­ure out how his­tory will rhyme with the future.

If you were to look at the recent his­tory of the 2001 reces­sion, earn­ings dropped 54% from their highs to their lows. If S&P 500 reported earn­ings were to drop by the same amount this time around they’d be at about $39. We are already below that level, 2008 esti­mates for S&P 500 were revised down again, now to $28. How­ever, this is where Twain’s rhyming think­ing becomes impor­tant — note that in 2001 earn­ings went only 18% above the “aver­age case” line; in 2007 they were 31% above that line. If we were to fol­low the higher they climb the harder (deeper) they fall logic, this would lead us to believe that earn­ings will drop fur­ther this time, esti­mates for early 2009 earn­ings indi­cate that.

When will we see aver­age earn­ings?
The good news is S&P “aver­age case” earn­ings are about high $70s to low $80s a share (see big red squares in yel­low shaded area) — which would make the mar­ket cheap (with a PE of about 10). But here is the bad news (don’t shoot the mes­sen­ger please) — we just won’t see those “aver­age case” num­bers for a while.

The 2001 reces­sion was dri­ven by the over­ca­pac­ity in the cor­po­rate sec­tor. Cor­po­ra­tions ratio­nal­ized their inven­to­ries and fac­to­ries, higher unem­ploy­ment fol­lowed — we were in a reces­sion. Excesses were worked out, cor­po­ra­tions started to hire, and voila — we were out of the reces­sion. Of course the recov­ery process was also aided by a “friendly” Fed, it took inter­est rates to (at the time) an unprece­dented low lev­els and kept them there until cor­po­ra­tions and con­sumers got seri­ously drunk on cheap money and spent them­selves into seri­ous debt for which we are pay­ing now.

In the 2001 reces­sion it took two and a half years for earn­ings to rise from their bot­tom to their average.

Unfor­tu­nately we’ll not be that lucky this time — we are in a con­sumer reces­sion. Con­sumers are two thirds of the econ­omy and they are delever­ag­ing. As a side note: This delever­ag­ing goes beyond big ticket dis­cre­tionary items like large screen TVs and SUVs. Now it is show­ing up in lower con­sump­tion of sta­ples like iced tea by Snap­ple which com­petes with cheap­est com­mod­ity of all — tap water. Now, more expen­sive branded prod­ucts like dia­pers and tis­sue made by Kim­berly Clark are forced to com­pete with generic store brands. The mean­ing of the word sta­ple is being rede­fined by this economy.

The Fed, being even “friend­lier” than the last time, has low­ered inter­est rates to almost zero, buy­ing long-term bonds etc. But this time around the Fed’s booze will not do the trick — con­sumers are still suf­fer­ing a hang­over from the last Fed’s “help” — they don’t want to bor­row and banks, after incur­ring huge losses, are behav­ing like real banks — only giv­ing loans to peo­ple who’ll pay them back.

In addi­tion to con­sumer delever­ag­ing, gov­ern­ment debt is sky­rock­et­ing with every bailout, thus taxes and inter­est rates are likely to be sig­nif­i­cantly higher once the econ­omy normalizes.

The Earn­ings recov­ery will likely take longer than many expect, there­fore, there is a very high pos­si­bil­ity that the “aver­age case” earn­ings growth going for­ward will be below the his­tor­i­cal aver­age of 6%

Are we about to embark on a sec­u­lar bull mar­ket?
The mar­ket is a dis­count­ing mech­a­nism — stocks will rise in the antic­i­pa­tion of a future earn­ings rebound, before the rebound. Sim­i­lar to the stock mar­ket fore­cast­ing ten out of the last three reces­sions, it will dis­count a few recov­er­ies before the real one takes hold.

What does this mean? We’ll likely have a few “fake” head starts and dis­ap­point­ments before the actual earn­ings recov­ery takes place.

As I argued in my book Active Value Invest­ing: Mak­ing Money in Range-Bound Mar­kets, we are very likely in the midst of a sec­u­lar range-bound (trend­less, volatile but going nowhere) mar­ket that started in early 2000. His­tor­i­cally, range-bound mar­kets started at the end of the sec­u­lar bull mar­ket when P/Es were above aver­age. They ended when P/Es stopped declin­ing (mean revert­ing), after a visit to below aver­age ter­ri­tory (around 10–11 or less). The cur­rent range-bound mar­ket started at much above aver­age val­u­a­tion and will likely rhyme with the past fin­ish at below aver­age val­u­a­tion as well.

Based on the Pain of mean rever­sion chart we are trad­ing some­where between 30 and 10 times earn­ings. How­ever, nei­ther num­ber is very mean­ing­ful. Let me explain:

2008 esti­mates of $28, the “E” in P/E of 30, are dis­torted by mas­sive charge offs.

The “aver­age case,” the “E” ($80) that went into P/E of 10, lies in a far away land that … well, let me put it this way, you and I will get to grow sick of pres­i­den­tial cam­paign adver­tise­ments at least once or maybe even twice before that “E” is in sight.

Even based on 2010 “E” esti­mates ($40) stocks in the S&P 500 are trad­ing at 21 times earnings.

Despite the decline, the mar­ket is still not cheap. Sorry, we are not likely to embark onto the new sec­u­lar bull mar­ket any­time soon. His­tory and data sug­gest that the choppy mar­kets that we have seen since 2000 will likely con­tinue. Own­ing a broad mar­ket index will not pave a road to pros­per­ity. It comes down to not just own­ing stocks but own­ing the right stocks.

P.S. As a side note I believe sig­nif­i­cant earn­ings write-offs will con­tinue well into next year as finan­cial stocks will pass their write-off torch to com­pa­nies in energy, mate­ri­als and indus­trial sec­tors — stuff stocks — that will be writ­ing off the invest­ments they’ve made over the last five years.

By the time, I fin­ished putting these thoughts together, which on and off took about two weeks, 2008, 2009 and 2010 esti­mates were taken down by about 20–25%.

If you missed it, Vitaliy did three 5 minute seg­ment inter­views on Yahoo TechTicker on Tues­day with Aaron Task and Henry Blodget.
