Shares RSIs, highs and lows

Our regular look at shares trading at significant levels.

Supergroup’s 14% slump yesterday has carried it into oversold levels, after the company said that sales had been hit hard by a late Easter and a reduction in sales through the online auction site eBay. We saw the shares slump 20% in April, as this high growth and high momentum stock fell out of favour with investors. Last year was a good one for the company, so it is admittedly struggling against difficult comparisons, but the slowdown in volumes is worrying news.

Gold miner Petropavlovsk is also oversold, and rapidly heading towards a retest of the 65p low that was seen in January. A drop through here means we could see the shares fall to 55p, the all-time low in what was a very impressive downtrend.

Copper miner Antofagasta has finished with its latest bounce and is now dropping back towards 52-week lows. Although the price of the red metal has gained in recent weeks concerns about output from Antofagasta remain, and this is driving the share price lower. In my view, 765p and the 750p are the short term targets on the downside 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.
