Question

What is the best way to determine the P/E ratio for a specific stock?

Need help with a formula calculation. I have the value for net worth, but I am having trouble iterating over the EPS values and multiplying them by the shares held. Can anyone suggest a solution? Thank you! You can find the Plunker here

        <div>
            <h3>P/E Ratio: {{getNetWorth())}}
        </div>

Here is the script snippet:

$http.get('data.json').then(function(response) {
     $scope.stocksArray = [];
     var indexes = [];
     var epsindex = [];
     var eps = {};
     $scope.eps = response.data.eps;

Answer №1

Although it may not receive any accolades, you can find the essence of the issue here.

Your json file has an unusual structure:

  -price
    --stock-name:stock-price
  -eps
    --stock-name:stock-eps

The structure should be like this:

  -stock-name
    --price:actual-price
    --eps:actual-eps

This adjustment would allow you to import it as objects without having to manually instantiate the entire collection. I worked with the given data and it functions correctly.

The crucial part is in the next two lines:

$scope.eps = response.data.eps;

AND

mystock.eps = $scope.eps[key];

By including the eps collection as a separate array, I was able to incorporate it as a field in the object property.

Implementing getPortfolioPE() was straightforward:

$scope.getPortfolioPE = function(){
          let temp = 0;
          let total = 0;
          for(let i = 0; i < $scope.stocksArray.length; i++){
            total += $scope.stocksArray[i].eps * $scope.stocksArray[i].shares
          }
          temp += $scope.getNetWorth()/ total;
          return temp.toFixed(2);

        }

In my opinion, the $http.get function should be set up to retrieve an array of stocks where the PE ratio is a property of each individual stock.

Therefore, the controller code should look something like this:

$scope.stocks = response.data;

Additionally, in the template, you will likely need to use ng-repeat to iterate through the array of stocks and display the PE ratios:

<li ng-repeat="item in stocks">
    Your PE ratio is: {{item.pe}}
</li>
