is there an indicator similar to weighted alpha, but works with shorter periods of time, instead of the 52 weeks of weighted alpha?

The deep research logic is organized as follows: 

Okay, let's tackle this question. The user is asking if there's an indicator similar to weighted alpha but with shorter time periods than the usual 52 weeks. First, I need to recall what weighted alpha is. From the references, weighted alpha measures a security's performance over a year, giving more weight to recent data. It's used by technical analysts to identify trends and make trading decisions.

The user wants something similar but for shorter periods. So, I should look for indicators that focus on recent performance but over less than a year. Let's go through the references provided.

References 1, 2, 4, 5, 6, 7 all discuss weighted alpha, but they don't mention shorter periods. However, reference 6 mentions that the time period can be adjusted, but the example given is still a year. Reference 7 also notes that the period can vary, but the standard is a year.

Looking at other indicators, reference 8 lists top trading indicators, including momentum indicators like RSI, MACD, and Bollinger Bands. These are commonly used for shorter-term analysis. For example, RSI is typically calculated over 14 days, which is much shorter than 52 weeks. Similarly, MACD uses 12 and 26-day periods. These could be good candidates.

References 13, 14, 15, 16, 17 discuss momentum indicators in detail. Momentum indicators are designed to capture recent price movements, which aligns with the idea of a shorter period. The Time Series Momentum Effect (reference 17) specifically uses past returns to predict future performance, often over 12 months, but it's adaptable to shorter periods.

Also, the 52-week high effect (references 18, 19, 20, 21, 22) is related but focuses on the 52-week range. However, the user is looking for something shorter, so maybe the 52-week high effect isn't the answer here.

Another angle is the use of moving averages with shorter periods. References 9, 12 discuss moving averages, like 50-day or 200-day, but these are trend indicators, not exactly the same as weighted alpha. However, they do focus on recent data.

Putting this together, the indicators that fit the user's request are momentum indicators like RSI, MACD, and the Time Series Momentum Effect. These can be adjusted to shorter periods (e.g., 14 days for RSI, 12-26 days for MACD) and focus on recent performance, similar to weighted alpha but over shorter time frames.

I should structure the answer by first defining weighted alpha, then introducing the alternatives with shorter periods, explaining each indicator, their calculations, and how they align with the user's needs. Also, considering the user's interest in tech stocks like NVDA, GOOGL, and BABA, these indicators are widely used in short-term trading strategies which might be relevant to their portfolio.

Make sure to cite the relevant references, especially those that discuss the indicators and their time periods. Also, include a visualization for the weighted alpha query if applicable, but since the user is asking for alternatives, maybe a table comparing the indicators would be helpful.

### 🌟 **Conclusion**
Yes, there are several indicators similar to **Weighted Alpha** that focus on shorter time periods, providing insights into recent price movements and momentum. These include **Momentum Indicators** (e.g., RSI, MACD) and **Time Series Momentum Strategies**, which can be adapted to shorter windows like 14 days or 1 month instead of the traditional 52-week period .

### 📊 **Analysis**
#### 1. **Key Differences Between Weighted Alpha and Shorter-Period Indicators**
| Metric | Weighted Alpha (Typically 52 Weeks) | Shorter-Period Alternatives (e.g., 14 Days or 1 Month) |
|------------------------|-----------------------------------------------|---------------------------------------------------------------|
| **Time Frame** | 1 year (52 weeks) | 14 days, 1 month, or custom shorter periods |
| **Focus** | Recent performance weighted more heavily | Recent price momentum or volatility |
| **Use Case** | Long-term trend analysis | Short-term trading signals (e.g., entry/exit points) |
| **Calculation** | Weighted sum of daily returns over 1 year | Momentum-based formulas (e.g., RSI, MACD) or price deviations |

---

#### 2. **Top Shorter-Period Alternatives**
| Indicator | Description | Formula/Key Metric | Common Time Frames |
|-----------------------|-----------------------------------------------------------------------------|-----------------------------------------------------------------------------------|-------------------------------|
| **RSI (Relative Strength Index)** | Measures overbought/oversold levels based on average gains/losses. | RSI = 100 - (100 / (1 + Average Gain/Average Loss)) | 14 days (default), 7 days |
| **MACD (Moving Average Convergence Divergence)** | Tracks price momentum using exponential moving averages. | MACD = (12-day EMA - 26-day EMA), Signal Line = 9-day EMA of MACD | 12/26 days, 5/20 days |
| **Time Series Momentum** | Predicts future returns based on recent price trends. | Momentum Score = Past 12-month excess return (adaptable to shorter periods) | 1 month, 3 months |
| **Stochastic Oscillator** | Identifies short-term overbought/oversold conditions. | %K = (Current Price - Lowest Price) / (Highest Price - Lowest Price) × 100 | 14 days (default) |

---

#### 3. **Why These Alternatives Work for Shorter Periods**
- **Momentum Focus**: Unlike Weighted Alpha, which averages performance over a year, these indicators isolate **recent price action** to capture short-term trends .
- **Flexibility**: Time frames can be adjusted (e.g., 14 days for RSI, 1 month for Time Series Momentum) to align with the user’s interest in **short-term trading** .
- **Practicality**: These indicators are widely used in platforms like TradingView and Quantpedia, making them accessible for real-time analysis .

---

#### 4. **Example Application for Tech Stocks (e.g., NVDA, GOOGL)**
For a stock like **NVDA**, a **14-day RSI** could help identify oversold conditions (below 30) or overbought levels (above 70) . Similarly, a **1-month Time Series Momentum** score could highlight stocks with strong recent performance (e.g., past 30-day returns) .

### 📊 **Comparison Table**
| Metric | Weighted Alpha (52 Weeks) | RSI (14 Days) | Time Series Momentum (1 Month) |
|------------------------|---------------------------------------|-----------------------|-----------------------------------------|
| **Calculation** | Weighted sum of daily returns | Average gains/losses | Past 12-month excess return (adaptable) |
| **Use Case** | Long-term trend analysis | Short-term momentum | Predictive price trends |
| **Example** | NVDA’s 1-year performance | NVDA’s 14-day RSI | NVDA’s 1-month momentum score |

---

### 🌟 **Final Takeaway**
For shorter-term analysis, **RSI**, **MACD**, and **Time Series Momentum** are ideal alternatives to Weighted Alpha. These indicators provide actionable insights into recent price trends and can be tailored to align with the user’s focus on **US Tech stocks** like NVDA and GOOGL .
