Jeremy Grantham's Warnings to Investors

Jeremy Grantham

Of the thousands of investment letters penned in the industry, only one draws as much readership as Warren Buffet’s annual letter to his shareholders: The quarterly commentary written by Jeremy Grantham.

Grantham, the Chairman of the Boston-based investment firm Grantham Mayo Van Otterloo, was a featured speaker at Morningstar’s Investor Conference last week, and he spoke at two breakout sessions.  Those who, like me, attended both were richly rewarded, as he gave two distinctly different talks, addressing many subjects not covered in his commentaries.

Grantham’s March quarterly commentary was titled “Reinvesting When Terrified,” which he says he wrote for himself – not for anyone else.  Beginning in February, he sensed a déjà vu of 1974, when he felt he had lost the power to make changes.  That bear market, like the most recent one, “hugely reinforced” the resolve of those who held cash as the market when down, and left those fully invested praying for a miracle. 

He concluded there was only one answer: follow a simple battle plan (“plans that are too fancy mess you up”) where the key decision was how cheap the market would have to get for investors to “throw in all they have.”  Otherwise, he said, if market opportunities evaporate, so does enthusiasm.

But Grantham did not advocate “throwing in” everything at once, instead recommending a three-step plan, gradually increasing equity allocations to their normal levels as the market neared its target valuation.

In his standard asset allocation accounts, for 19 of the last 20 years he maintained a 50% allocation in global equity, to facilitate the marketing of his funds.  By October of 2008, the market had declined to his first trip point, and he increased equity allocations by 7.5%.  Later that year, when the S&P hit 740, it reached his second trip point, and Grantham increased equities by another 7.5%.  The final move occurred very close to the market bottom, when the S&P reached 666.

Grantham almost over-weighted US and global equities, which he said were overpriced for most of last 20 years, and were close to becoming undervalued.

Grantham called this discipline “Plan A,” which he said was absolutely critical.  “Most of us fail and are left behind.  That’s what I was writing about – when you are left behind it causes panic.”

Those who fail at Plan A must follow Plan B:  “You take a deep breath, recognize you lost round one, and plan to take a year to 15 months and average into the market,” he said.  “Give the market plenty of time to have second thoughts.  You may win a few months and lose a few months.”

Locking yourself in – staying in cash – and praying for a major setback is a mistake which Grantham called “regret minimizing.”  On the other hand, if you barrel in, you are exposed to the market overcorrecting.  “Either way you are screwed,” he said.  “You have to balance those regrets.  That is the real world.”
