Shares RSIs, highs and lows

A regular look at shares trading close to significant levels.

Yesterday’s selloff has done nothing for those shares already beaten down by recent bad news, and this has meant that our oversold list has not seen much change. Defence firm Qinetiq is on the list too, the shares having slumped in recent days. They are now touching 195p, the lowest level in over six months, and sit on key support from mid-November 2013.

Although not much changed today, United Utilities has touched highs not seen since 1999 this week. 876p remains the major upside resistance, but it seems in these times of heightened volatility the appeal of a secure utility company with a strong dividend should not be underestimated.

Speaking of utilities, the same factors are driving National Grid. In addition, US investors in the company are picking up the shares again as Treasury yields drop back. Grid’s rally last year was torpedoed by a rise in yields that made US government bonds more attractive, but now it seems yields are heading lower, boosting the appeal of National Grid shares as an income investment as well as a capital one.

*What is a relative strength index?

Relative strength index is a technical momentum indicator that compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an asset.

An asset is viewed as overbought once the RSI approaches the 70 level, meaning that it may be getting overvalued and is a candidate for a possible pullback. Conversely, if the RSI approaches 30, it is an indication that the asset may be oversold and may become undervalued.

**What is the significance of 52-week highs and lows?

One popular strategy is to buy when shares exceed 52-week highs and sell when they fall below 52-week lows.
