Q1.5, Plot the closing price vs date graph. (pick the command that you used to plot the graph in Camino)

Question

BlackTom AI · Accepted Answer

Here, we need to choose the command that plots the closing price versus date for the Camino dataset.
Option 1: 'stock_c.shift(-1).plot()' would shift the series by one period before plotting. This distorts the alignment of dates with their corresponding closing prices, so it’s not appropriate for plotting the actual closing price over time.
Option 2: 'stock_c.plot()' directly plots the closing price series 'stock_c' against its index, which typically represents dates. This aligns each closing price with the correct date, producing a closing-price-vs-date plot.
Option 3: 'stock_o.plot()' would plot the opening price series, not the closing price, so it fails to meet the requirement of plotting closing prices.
Option 4: 'stock.plot()' is a more generic command that would plot the entire stock object or a default series, which may not specifically represent the closing price and could be ambiguous depending on the data structure used.
In summary, the most appropriate and precise choice for plotting closing price versus date is option 2, 'stock_c.plot()' since it targets the closing price series directly.
