Why investors need to read between the lines of rumour and news

Joe Chidley: The short-lived run-up in oil prices last month is an example of how the lines between news, rumour and noise are getting blurrier all the time - making following old investing adages a dodgy enterprise.

Here’s an investing rule for you: Be wary of pearls of wisdom. Any “pearl” that can be summarized in six words or less may have the advantage of making life easier, but often that’s about this, and following these items of the usual understanding too closely can be a recipe for disappointment.

How to beat interest rate uncertainty if you’re purchasing stocks

It’s accepted as dependent on proven fact that markets hate uncertainty. Most investors, given an option, like to know what they’re dealing with, and also the smart ones (e.g. Warren Buffett) look for companies that offer steady cash flows, a sustainable competitive advantage and also the financial strength to withstand storms.

Take “Buy low, sell high,” for example. Sure, it sounds good. But what’s your definition of low? What do you mean by high? There can be a greater to follow your selling, or perhaps a lower to follow along with your buying.

Another adage often bandied about available trading is “Buy the rumour, sell the news.” It basically assumes that asset prices will rise in anticipation of news developments (the rumour phase), and decline following news developments as investors place their profits. So the time for you to “get in” is during the rumour phase, when there’s high upside to news developments.

In a world of nearly instantaneous news dissemination, obviously, the lag from a rumour and a bit of actual news is getting smaller constantly. What feels like rumour soon becomes noise, which after a while begins to appear to be news. The media cover the noise, that isn’t really news. Even when the underlying rumour has been largely discredited or undermined by other developments, the noise can persist, and continue to have an impact on asset prices.

Consider the short-lived run-up in oil prices around the end of recently, when benchmark WTI briefly neared US$34 a barrel. To my mind, it’s an example of how the lines between news, rumour and noise are becoming blurrier all the time – making following old investing adages a dodgy enterprise.

If you remember, the move came amid speculation the Russians and/or the Saudis and/or the entire Organization of Petroleum Exporting Countries (OPEC) were available to production cuts to create stability to oil markets.

The source of the speculation would be a comment from Russian Oil Minister Alexander Novak on Jan. 28. He told reporters that OPEC had proposed a five-per-cent cut among major oil producers (OPEC and non-OPEC members, like Russia, included), and implied that the proposal was being led by Saudi Arabia. Or, rather, when asked whether this proposal had come from Saudi Arabia, he didn’t say no.

The result: a flood of reports that the Saudis and Russia were about to agree with 5 percent solution, and benchmark crude prices jumped almost 10 %.
