All Technology Assets

Mostly expectations for earnings growth. Because much of a technology company's value rests on profits expected years ahead, these stocks tend to react strongly to changes in interest rates and to guidance on demand, such as data-centre and chip orders, software subscriptions and device sales.

Investors pay more per dollar of current earnings when they expect those earnings to grow quickly. A high P/E is not a verdict on its own: each page compares the company's P/E and price-to-sales ratio with the median of the technology stocks CleaRank tracks.

Sector funds such as the Technology Select Sector SPDR (XLK) hold the large US technology companies, while semiconductor funds such as SMH and SOXX focus on chipmakers. The Invesco QQQ Trust (QQQ) tracks the Nasdaq-100, which is technology-heavy but also holds companies from other sectors. Each fund has its own page with its holdings, fees and returns.

It varies widely by company. Large, established software and hardware companies can move much like the broader market, while smaller semiconductor, quantum-computing and early-stage software names can move several times as much. Each page shows the stock's typical daily move and its worst fall in its price history.

Each asset's analysis, technical indicators and ratings are rebuilt once a day, and prices are refreshed several times a day. Every page shows the date of its figures, so you can see how current each one is.
