Pisani: One simple way investors can keep riding the market higher

Pisani: Great week overall

Friday is a consolidation day, with beaten-up defensive groups like real estate, utilities and consumer staples up fractionally.

The market leaders — banks, industrials and materials — are taking a back seat.

The S&P 500 is poised for its first down week in about a month.

Does that signal the start of a correction? Don't kid yourself. There are almost no bears. The uptrend is very much intact.

But beneath the rally, there has been furious churning. There have been winners and losers.

Investors could have done one simple thing to win without doing anything: stay long the broad market.

Call it Jack Bogle's revenge.

If you just owned two ETFs — the (SPY) and the iShares Russell 2000 (IWM) — you'd be sitting at all-time highs, and all this talk about rotating out of consumer staples, real estate and emerging markets and into banks, industrials and materials would be of no real consequence to you.

If you owned those two ETFs, you'd be owning practically the entire market.

"The action in the last month really demonstrates the futility of owning sectors," said Alec Young, an independent strategist formerly with S&P and Oppenheimer. "We talk about all this rotation, but how many investors have really been able to call this turn? Even the professional investors have had a hard time. For most investors the best play is to own the broad market."

Fortunately, that's what a lot of people decided to do. There have been significant inflows into S&P 500 and small-cap (Russell 2000) ETFs, but there have also been significant inflows into financials (XLF), industrials (), and significant outflows from emerging markets (), gold (GLD) and consumer staples (FXG). This week, we also saw outflows from select technology ETFs like semiconductors (SMH).

So you would have made a lot of money if you would have rotated out of a bunch of sectors and into another bunch of sectors.

But almost no one did that. You could have stood pat and stayed long.

That, Young says, is a vindication for all the traders and funds who have argued against furiously trading in and out of positions.

Said Young: "It's a great marketing opportunity for Vanguard."
