The article you provided contains information about several stocks that are moving lower in pre-market trading on Tuesday. Here is a summary of the main points:

1. ACADIA Pharmaceuticals Inc reported negative results from its Phase 3 ADVANCE-2 trial for treating schizophrenia, causing its shares to fall by 17.4% in pre-market trading. This is a high-risk investment due to the failure of the trial and the potential impact on the company's future revenue and reputation.

2. Power & Digital Infrastructure Acquisition Corp II saw its shares drop by 12.6% after surging 181% on Monday, which indicates a high level of volatility and speculation in this stock. This is also a high-risk investment due to the lack of clear fundamentals and the uncertainty surrounding the merger with a target company.

3. Ocular Therapeutix Inc reported disappointing fourth-quarter financial results, leading to a 5.9% decline in its shares in pre-market trading. This is a moderate-risk investment due to the negative earnings report and the potential for further downside if the company fails to improve its performance.

4. Aeva Technologies Inc announced a 1-for-5 reverse stock split of its outstanding shares, which could indicate financial difficulties or a lack of investor interest. This is also a high-risk investment due to the potential for further dilution and the uncertainty surrounding the company's technology and market position.

5. PLDT Inc saw its shares fall by 3.8% after jumping over 16% on Monday, which suggests a high level of volatility in this stock. This is a moderate-risk investment due to the fluctuations in share price and the potential for further swings based on market sentiment and news.

6. NextNav Inc announced an agreement to acquire spectrum licenses, which led to a 3.6% decline in its shares in pre-market trading. This is a moderate-risk investment due to the mixed signals from the market and the uncertainty surrounding the value of the acquired spectrum.

7. Lexicon Pharmaceuticals Inc said it is preparing to resubmit its Sotagliflozin NDA for Type 1 diabetes, which caused its shares to fall by 3.2% in pre-market trading. This is a moderate-risk investment due to the previous rejection of the NDA and the potential for further setbacks or delays in the approval process.
