Shares in Britvic (LON:BVIC) have been on a huge run in 2019. With the company's half-year results due out in May, the the question for investors is how its share price is likely to respond.
Finding stocks that can break-out and move higher on news updates is a tactic used by some of the world’s most successful traders. But it’s not a black-box strategy…
Indeed, knowing the factors that drive relative strength in share prices can help you find profitable momentum trades, too. I’m going to use Britvic as an example of how this can work.
How has the Britvic (LON:BVIC) share price performed?
Britvic is a conservative, large cap in the Non-Alcoholic Beverages industry and it has a market cap of £2,523m.
Over the past year, the Britvic share price has risen by 40.6%, which sounds impressive.
But it’s important to put this in context and look at the market trend. After all, in a rising market where prices are up across the board, that gain might not be as remarkable as it seems.
As it turns out, the FTSE All-Share index is up slightly over the past year, so Britvic's shares have a 1-year relative strength of 37.3%.
Why relative strength really matters
Relative strength is a crucial tool in the armoury of technical traders and investors. It’s an instant measure of how a stock has performed in comparison with a benchmark.
And while there are no certainties about which way a stock will move next, research shows that price trends often persist.
Studies by Narasimhan Jegadeesh and Sheridan Titman, who are leading experts on momentum, show that stocks with the strongest price strength tend to keep up the pace for anywhere up to one year.
But what causes this?
The answer is that investor behaviour plays a big role. Academics point to two key drivers:
- Under-reaction - prices are slow to move up because investors are hesitant to bid prices higher in stocks that have already been on a strong run.
- Delayed over-reaction - investors chasing rising prices attract the attention of other investors, who follow them into those trades, pushing prices higher and higher.
So the answer is that momentum in stocks with strong relative strength is at least partly caused by a virtuous circle of human emotion. Investors have to constantly re-price these improving shares in their own minds.
It won’t always happen - and it might take some time - but when momentum takes over, it can push prices higher and higher.
Next steps
Britvic has clearly been on a strong run recently. Research into momentum suggests that kind of price trend has the potential to continue. But it’s important to remember that while momentum is a powerful driver of stock market returns, it can be also prone to strong pull-backs when sentiment changes - so care is needed.
