The last few weeks of cascading share prices may be troublesome to most investors, but Cathie Wood doesn't mind buying during the deluge. The co-founder, CEO, and investment manager at Ark Invest has been more active lately in buying shares for her high-octane growth exchange-traded funds.

Thursday was another busy shopping day. Ark added to existing positions in Tesla (TSLA 1.77%), Iridium Communications (IRDM -0.29%), and Intellia Therapeutics (NTLA 0.11%). Let's take a closer look at the these three stocks that have had steep pullbacks in recent weeks.

1. Tesla

It's been three months since Tesla hit an all-time high heading into the holidays, with CEO Elon Musk becoming a prominent political figure after the November presidential election. The stock has shed more than half of its peak value. It's been a rough run for the country's leading maker of electric cars. Sales were flat last year after a decade of consistent double-digit growth. It has also missed Wall Street's profit estimates in three of the last four quarters.

There is some good news despite the sell-off. Despite the notion that Musk's political turn may be hurting the brand internationally and alienating many stateside drivers, the market sees Tesla returning to double-digit growth this year. It also has more in the hopper than its current slate of vehicles. The stock has moved higher in the last two trading days, fueled in part by a timely analyst upgrade.

Andres Sheppard at Cantor Fitzgerald shifted his sentiment from neutral to bullish. He is sticking to his earlier $425 target, but that represents 80% of upside from current levels.

Sheppard sees several catalysts coming into play in the near future. More affordable Tesla vehicles will start to be produced in the second quarter. The debut of Tesla's Cybercab robotaxi business is on track for volume production come next year. Advances in Tesla's self-driving platform continue to roll out with each over-the-air upgrade. It will take longer for its Optimus robots to hit the market, but the promise of home bots that can complete household chores is a huge market that can help smooth out the cyclical swings of the auto market.

2. Iridium

3. Intellia Therapeutics

Wood has been a steady buyer of gene-editing stocks, a thin slice of the biotech market but also a segment with the most promise and upside. Intellia Therapeutics is a developer of CRISPR-based therapies tackling rare but devastating genetic disorders. If you think Tesla and Iridium have been hard on investors lately, Intellia is far worse. The stock has plummeted 96% -- yes, 96% -- since peaking north of $200 almost five years ago.

Mitchell Kapoor at Wainwright initiated coverage of Intellia earlier this month with a bullish rating and a $30 price target. He's encouraged by its NTLA-2002 candidate that offers a one-time treatment as opposed to comparable solutions that are drawn out prophylactic therapies with the same efficacy. Another bull -- Joon Lee at Truist -- lowered his firm's price target from $90 to $50. It's not usually a good sign when a target price is lowered sharply, but with Intellia now trading in the high single digits it would have to more than triple to hit the first $30 goal and soar almost sixfold to hit the other analyst's revised goalpost.
