Shares RSIs, highs and lows

A regular look at shares trading close to significant levels.

Although it is bouncing this morning and appears to have found a floor at £21, Rightmove is still on our oversold list. The listed property website has enjoyed a phenomenal rally, but now talk of curbs on the housing market is causing investors to book gains. There appears to be little support for the share price in the longer term and only £20 on the weekly chart provides some hope. Should that disappear then £14.30 is the next stop, which would signal a loss of all of 2013’s gains.

National Grid is overbought this morning, as it touches fresh all-time highs. We have seen the shares move above the December 2007 peak, easing fears that investors could become jittery around this level. BG Group has returned to its overbought state, after dipping lower last week. £12.82 has provided some resistance, but the shares are currently above this level, which signals a possible retest of the January high at £13.50.

National Grid has dropped back from its fresh high, but the important thing is that it is above both its high from 2013 and the one from 2007. This signals that there remains significant buying pressure in the stock. However, for Dairy Crest, buyers are in short supply as sentiment turns sour on the milk producer. Although it is off the lows of last week the shares still look weak, and 446p, the lows of June and September 2013, is the level to watch.

*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.
