The information technology sector has the highest weighting in the S&P 500 index, representing more than a quarter of the index’s market cap. Over the last decade, the sector has been “hot” and had a spectacular bull market.
In this article, we take a brief look at the biggest stocks in the sector, and we make a technology sector trading strategy (actually we make two technology sector trading strategies). The technology sector is a very good trading vehicle.
Let’s take a look at the sector and do some backtests.
What is the S&P technology sector?
The S&P 500 Information Technology sector consists of those companies included in the S&P 500 that are classified as members of the GICS information technology sector — a sector that covers companies that develop or distribute technological items or services, including computers, microprocessors, and operating systems.
While some companies in this sector focus on creating software or providing services related to implementing technological solutions, others are more involved in building the equipment, components, and hardware that make tech possible. So, the sector also includes makers of semiconductors and the equipment used in producing semiconductor chips.
The major ETFs that track the Information technology sector include the Vanguard Information Technology ETF (VGT) and the Technology Select Sector SPDR Fund (XLK).

Let’s go on to backtest some technology trading strategies:
Technology sector trading strategy no. 1 (XLK trading strategy)
All the backtests in the rest of the article are done on the ETF with the ticker code XLK.
The first technology trading strategy is based on two trading indicators. They can both be labeled oscillating indicators and both are based on mean reversion. It’s two variables for when to buy, and one simple variable for the exit. We buy and sell at the close:
The equity curve looks like this:
The number of trades is 245, the average gain per trade is 0.96%, CAGR is 10% (buy and hold is 8%), time spent in the market is 12%, max drawdown is 18%, the win rate is 71%, and the profit factor is 3.1.

Technology sector trading strategy – ending remarks
One of the most important things in trading is to focus on the “low hanging fruit”. This is one of the most important lessons from Jim Simons, and he referred to mean reversion strategies. Mean reversion works great for broad market indices like S&P 500 and QQQ, but also for the technology sector.
In this article we made 2 technology trading strategies – both based on mean reversion. However, any technology sector trading strategy might correlate strongly with the broader market and thus offer very little diversification benefits.
