Viners, what are your stock investment principles?

For those actively engaged in direct stock investments, what guiding principles do you adhere to? Personally, my portfolio lacks structure; I tend to purchase stocks whenever funds are available, resulting in an overly diverse spread across approximately 30 stocks that I'm looking to consolidate. I aim to adopt a more disciplined approach and identify areas for improvement. Are you an active stock investor? Do you adhere to a regular investment interval and budget? Do you impose an upper limit on the number of stocks in your portfolio? If so, how do you handle adding a new stock? Do you skip the new addition, or do you exit an existing one? When investing, do you consistently allocate multiples of the same amount, or does it vary? When entering a stock, do you make a single purchase or spread it over multiple days? Do you adjust your stake in existing stocks? If so, what criteria guide your decision to increase or decrease your stake? Upon exiting a stock, is it done in one shot or over several days? Does the dividend yield influence your stock selection, and do you have a specific dividend target? Do you use external services like Excel, Value Research, Markets Mojo, etc., to track your stocks? Where do you conduct your research? Platforms such as Screener, ValuePickr, MoneyControl, etc.? Do you have a specific metric for evaluating portfolio performance, such as absolute returns or CAGR? Are there any additional strategies you follow in your stock investments?

Goldman Sachs

This Research Paper changed my life forever.

It was one of the papers that was discussed in my interview at Goldman. I came to know about this research paper a few years back after consulting a friend doing an ML PhD at University of Maryland, College Park. The explanation of the paper: 1. Initialize the neural network with small random values typically (-0.1,0.1) to avoid symmetry issues. 2. Now get ready to do Forward propagation: you pass thetraining data through the multilayer perceptron and compute the output. For each neuron in the MLP, calculate the weighted sum of its inputs and apply the activation function. (my favourite is tanh for LSTM applications) 3. Now compute the loss using a loss function like mean squared error, between output computed and the actual value. 4. Now get ready to do backpropagation, where you need to calculate the gradient of the loss function with respect to each weight by propagating the error backward through the network. 5. So, compute partial derivatives of the loss with respect to each weight, starting from the output layer and moving back to the input layer. 6. Here is the fun part: update the weights using the gradients obtained from the backward pass. here people usually use adam optimizer, which allows for accelerated stochastic gradient descent. Fun trivia: Adam stands for "Adaptive Moment Estimation". 7. Now repeat the forward and backward propagation process for numerous tries until theperformance of the model stabilizes.
