Jim Simons' s Profile & Performance

Profile

In 1982, Simons founded Renaissance Technologies Corporation, a private investment firm based in New York with over $20 billion under management; Simons is still at the helm, as CEO, of what is now one of the world's most successful hedge funds.

Investing Philosophy

For over two decades, Simons' Renaissance Technologies' hedge funds, which trade in markets around the world, have employed complex mathematical models to analyze and execute trades, many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.

"The advantage scientists bring into the game is less their mathematical or computational skills than their ability to think scientifically. They are less likely to accept an apparent winning strategy that might be a mere statistical fluke."

Sears Makeover Relevant to Online Shoppers
With a finger on the pulse of today’s shopper, Guru Edward Lampert has a gift for making retailers relevant to the ever-changing consumer. His retail re-visioning of Sears and Kmart is starting to pay off. Sears Holdings Corporation’s online businesses for Sears and Kmart grew 20% in the second quarter of 2013, year-over-year. Lampert’s brainchild, the Sears ‘Shop Your Way’ membership program, generated more than 65% of the revenues at Sears Domestic and Kmart during the second quarter, compared to around 55% in the same quarter a year ago. But despite e-commerce growth, Sears Holdings reported an operating loss of $51 million in the second quarter of 2013, after a loss of $103 million in the second quarter of 2012. Read more...
Insider Buys at 52-Week Highs
Several companies have reported group insider buying or pricey singular insider buying as their companies near or hit their 52-week highs. The following three companies have reported these insider buys throughout the month of July. Watching group insider buying (especially at high prices) is important because it can signify a collective faith in the stability and potential for additional growth in a company. It can also be beneficial to note insider buys with large transaction amounts because insiders typically will not invest their money into a company if they know they are going to lose it.

Four 'Boring' Stocks to Consider
The hottest stocks that receive the most coverage in the press are exciting to own, but investors are often in for a bumpy ride. Take for example Apple (AAPL), who had millions of eyes watching when the company released the iPhone 6 and 6 Plus. A snafu for a company like Apple can affect stocks in a major way, whether it’s warranted or not. On the other hand, companies in a relatively unexciting industry and those with a smaller, more regional presence often enjoy more stability without the daily press coverage. More...
