What stock under $15 is guaranteed to increase in price at least 100% in the next week

The deep research logic is organized as follows: 

Okay, let's tackle this question. The user is asking for a stock under $15 that's "guaranteed" to increase by at least 100% in the next week. Hmm, that's a bold claim. First, I need to check the references provided to see if there's any data that supports such a prediction.

Looking at the references, there are several queries related to stock prices, moving averages, percentage changes, and technical analysis. Let's start with the queries. 

Reference 1 and 2 are about stocks under $15 with specific moving average conditions and percentage changes. Reference 2 found Fortuna Mining (FSM) with a closing price of $7.43, which is under $15. The stock has a 1-week change of 28.08% and a 1-month change of 22.99%. The quantitative recommendation score is 0.77, which is decent but not extremely high. 

Then, looking at the other references, there's a lot of news about Fortuna Mining. Reference 4 mentions FSM hitting a 52-week high at $6.81 with a 55.71% YTD return. The company has a perfect Piotroski Score of 9, indicating strong financial health. They also sold some assets for $130 million, which could improve liquidity. 

Reference 16 and 13 talk about Fortuna being a growth stock with high EPS growth projections. The Zacks Rank is favorable, which is a good sign. However, the user is asking for a 100% increase in a week, which is extremely high. The recent performance shows strong gains, but 100% in a week is unrealistic unless there's a major catalyst. 

Looking at the technical analysis in Reference 26, FSM has a gap-up potential and a resistance level at $7.55. The last price is $7.43, so breaking above $7.55 could trigger some buying. But a 100% increase from $7.43 would take it to around $14.86, which is just under $15. The stock's recent volatility and positive news might push it higher, but 100% seems too optimistic. 

Also, the user's profile shows interest in NASDAQ and news-driven decisions. FSM is on the NYSE, so maybe not directly related, but the user might be looking for a high-growth stock regardless of the exchange. 

I need to check if there are any upcoming events or catalysts. Reference 7 and 12 mention no upcoming earnings or FDA approvals, so no immediate catalysts. The recent sale of assets could be a positive, but it's already priced in. 

Putting it all together, FSM is the only stock under $15 that meets some of the criteria, but a 100% increase in a week isn't supported by the data. The user might be looking for high-potential stocks, but the guarantee is impossible. I should explain the risks and why such a prediction isn't feasible, while highlighting FSM as a strong candidate based on recent performance and fundamentals.

### 🚨 **Conclusion** 🚨
**No stock under $15 is guaranteed to increase by 100% in the next week**, as such certainty defies the principles of market volatility and risk. However, **Fortuna Mining (FSM)** emerges as the most compelling candidate based on recent momentum, technical alignment, and fundamental strength. Let’s dive into the data.
