It's been a pretty good year for ASX 200 shares. The S&P/ASX 200 Index (ASX: XJO) has gained 7.7% to close at 7,196.70 points on Wednesday afternoon.
However, it hasn't been all good news across the index. In fact, here are 3 companies that have shed more than 50% of their value so far in 2021.
3 ASX 200 shares down more than 50% in 2021
1. Appen Ltd (ASX: APX)
One of the most surprising companies to make this coveted ASX 200 shares loser list. Appen shareholders have watched as more than 65% of the company's value has dropped away this year.
Shares in the data annotation company are now sitting at a 3-year low, having hit as low as $8.87 per share on Wednesday. One factor that has hurt Appen is the significant price run-up seen throughout 2020.
A pullback in growth shares amid rising bond yields has hurt the Appen share price. A disappointing FY21 earnings result, highlighted by a 55.1% drop in net profit after tax, hasn't helped the ASX 200 share in 2021.
2. Polynovo Ltd (ASX: PNV)
Another former ASX growth darling has made the list. The Polynovo share price has been smashed in 2021, falling 51.8% as at Wednesday's close. That's despite limited price-sensitive news from the Aussie company.
However, it appears that Polynovo may be falling for similar reasons to Appen – its recent share price growth has been significant. In fact, from 30 September 2020 to the end of last year, the ASX 200 rocketed 80% higher.
This year's pullback saw the Polynovo share price shed 30% in January alone after a sharp decline in first half sales from the Aussie biotech company. That downward trajectory has continued with the ASX 200 share's value continuing to decline.
3. AGL Energy Limited (ASX: AGL)
AGL may be a surprising addition to the list of share price decliners amongst two ASX growth shares. However, shares in the Aussie energy generator and retailer have slumped 51.6% lower since the start of the year.
2021 has been a tough year for AGL investors. A weak FY2021 result, highlighted by a statutory loss north of $2 billion, certainly hasn't helped boost sentiment.
Management has pointed the finger at the COVID-19 pandemic with increased supply coupled with weaker energy demand hurting the company's earnings.
