[...] MarketWatch and Motley Fool CAPS, Cake Financial and Social Picks are all sites which let investors create fantasy portfolios and track their performance. However, Covestor links your online portfolio to an actual brokerage account so there is real money at stake. As of October last year the site’s members were collectively managing $100 million worth of their own funds. [...]

Why “MarketPerception” is bad for investors…

While going through my daily routine of checking about a dozen or so blogs I found a very interesting story on Techcrunch about some new social features that Marketwatch is implementing. They have added the ability to vote on whether……

I agree - without considerdable investment;

- no one will care too much about how well - their pick is ..

- If they held contest; for free amount of $$ worth of investment on their site… or something ..
- that people could win -

I have heard the complaints about prediction markets like these being unnecessary because of the stocks price already public and should encompass any and all important information, but this feature allows users who don’t want to actually sign up on a an e*trade account, but may have some info that is predictive to participate in the market. In other words, I do have an opinion about certain stocks (especially retail), but do not want to actually commit $$.

As an Economist, I am attempting to do the same thing at http://www.finanicalnext.com for economic inidcators, if anyone wants to check it out.

Another experimental site trying to create a prediction market is http://fin.uti.ae. I wonder if any of these prediction markets have built a large enough and liquid enough information market to truly capture the market’s knowledge. And what happens with the few insiders who have a tremendous amount of valuable information on a company or stock but won’t or can’t share it with the community of the prediction market? Will the aggregated knowledge of the rest of the “lay” investors be enough to predict accurately?

Hi,

Does anyone know if the predictions shown for the top / worst 10 are from yesterday? None of them seem to be accurate when I click on them. How long does it take for them to update?

Why in the world would anyone bother to enter a guess without voting in the way they _want_ the stock to go?

I suppose if there’s a lot of voting and activity, it could be a sign that someone’s trying to manipulate a stock in the same way they do with spamed predictions. But that never means anything to the stock price either, so it’s hard to see any value at all in this.

Who need a stock predictor when you have the actual stock price as a way of knowing if it is going up or down.

Sorry I couldn’t help it.

I like MarketWatch, but even though I may be the worst investor in history, I will find it irresistible to chime in and vote for up or down on comapnies. I can’t see this helping the accuracy.

I am looking forward to the other community features that they are promising to launch later on. This MarketPerception tool may be good for fun and making predictions but I wouldn’t take its results seriously.

the details of the story are inaccurate…..marketwatch was a partnership between viacom and data broadcastiing corp, not bewteen viacom and dow jones. dow jones bought the whole thing a few years back, and ever since the site has gone downhill….less content, and slower. it used to be my homepage.

dow jones bought marketwatch as a free “gateway” into its paid subscription products…wsj.com, barrons.com, etc.

many of the key players that made marketwatch so great left soon after the dow jones acquisition.

I don’t think the ‘Wisdom of Crowds’ is just a voting technique, and I don’t see these yielding great results.

What makes the difference, is when it’s a group of individuals making decisions they actually have a stake in. Just voting or giving an impression means almost nothing. If you’d actually put money on the stock, that’s quite a bit better. And a crowd of people with money at stake is generally pretty good, like Tradsports for example.

I still think Marketocracy is the powerhouse social stock picking site. It is definitely worth a look. Tons of valuable info if you love stocks. I think the site needs a redesign, but the content is top notch!
